5NL Need help with a hand (I think I did it right this time ) :)

[crimson snapper]

Thanks to all who gave me advice on proper etiquette here earlier. I have one hand that I just played that is a prime example of what I see to be my biggest weakness. I've only been playing for 3 weeks but I seem to get trapped a lot with what I think are strong hands. I call the villain expecting to win and then I get pounded. What advice can you give me in general, and on this hand in particular that will help me determine when I should get out of a hand?
